This is incorrect sir. Of those 1000 planets found several are in the habitable zone of their host star. Once we launch the James Webb telescope we will be able to perform more precise spectral analysis and determine the chemical constituents. More than likely we will find life signatures that way.
Aside consider that most stars in the galaxy have multiple planets. The Milky Way may have more planets than stars. Most 'hot Jupiter' planets have exomoons in the habitable zones of their host stars. Moons like Titan, which have methane lakes and a weather system similar to earth, have anomalies that suggest alien life evolving in conditions completely alien to us. Water and carbon are found in abundance in the universe. Red dwarf stars can exist for trillions of years are the most common type of stars in our galaxy. Super earths, 3 times as massive as earth have been found and may be more favorable for life than earth itself. All these facts point to life existing everywhere and in all conditions. We will find life on multiple worlds and in moons in our solar system. Be thankful to be alive in a moment in history when we will discover all of this
This is the best out there right now. I'm sure things will change once the satellite launches but if scientists were to bet today this would take the pot. It's amazing to me how many factors go into finding a suitable planet. From what's around and even a Jupiter also.
A Nearby Super-Earth with the Right Temperature but Extreme Seasons

Gliese 832 c is the nearest best habitable world candidate so far
An international team of astronomers, led by Robert A. Wittenmyer from UNSW Australia, report the discovery of a new potentially habitable Super-Earth around the nearby red-dwarf star Gliese 832, sixteen light years away. This star is already known to harbour a cold Jupiter-like planet, Gliese 832 b, discovered on 2009. The new planet, Gliese 832 c, was added to the
Habitable Exoplanets Catalog along with a total of 23 objects of interest. The number of planets in the catalog has almost doubled this year alone.
Gliese 832 c has an orbital period of 36 days and a mass at least five times that of Earth's (≥ 5.4 Earth masses). It receives about the same average energy as Earth does from the Sun. The planet might have Earth-like temperatures, albeit with large seasonal shifts, given a similar terrestrial atmosphere. A denser atmosphere, something expected for Super-Earths, could easily make this planet too hot for life and a "Super-Venus" instead.
The
Earth Similarity Index (ESI) of Gliese 832 c(ESI = 0.81) is comparable to Gliese 667C c (ESI = 0.84) and Kepler-62 e (ESI = 0.83). This makes Gliese 832 c one of the top three most Earth-like planets according to the ESI (i.e. with respect to Earth's stellar flux and mass) and the closest one to Earth of all three, a prime object for follow-up observations. However, other unknowns such as the bulk composition and atmosphere of the planet could make this world quite different to Earth and non-habitable.
So far, the two planets of Gliese 832 are a scaled-down version of our own Solar System, with an inner potentially Earth-like planet and an outer Jupiter-like giant planet. The giant planet may well have played a similar dynamical role in the Gliese 832 system to that played by Jupiter in our Solar System. It will be interesting to know if any additional objects in the Gliese 832 system (e.g. planets and dust) follow this familiar Solar System configuration, but this architecture remains rare among the known exoplanet systems.
